Recruiting studies
- NCT05573893Recruiting
Real-world study of trastuzumab deruxtecan for HER2 breast cancer
This study looks at how people feel (patient-reported outcomes) and their real-world health data while they receive trastuzumab deruxtecan for advanced HER2-positive, HER2-low, or HER2-ultralow breast cancer. It helps researchers understand what outcomes happen outside of tightly controlled clinical trials.
AmbergAges 18–130 - NCT05524584RecruitingPhase 2
Anastrozole, fulvestrant, and abemaciclib for hormone-positive breast cancer
This trial tests whether combining three medicines can better control hormone-receptor–positive, HER2-negative metastatic breast cancer that cannot be cured with surgery or radiation. It may help shrink tumors and slow disease growth compared with standard hormone therapy approaches.
Orange, CaliforniaAges 18 years+ - NCT05512364RecruitingPhase 3
Elacestrant for ER-positive, HER2-negative breast cancer with ctDNA relapse
This trial tests whether elacestrant can help stop or delay breast cancer coming back in people whose blood test shows “ctDNA relapse” after early breast cancer treatment. It’s meant for hormone receptor–positive, HER2-negative breast cancer patients who are already taking hormone (endocrine) therapy and have no visible spread on scans.
AnderlechtAges 18 years+ - NCT05467891RecruitingPhase 2
Ribociclib plus hormone therapy for recurrent breast cancer
This trial tests whether adding ribociclib (a targeted pill) to hormone therapy can control breast cancer that has come back in the breast area or nearby lymph nodes/chest wall. It targets hormone-receptor–positive and HER2-negative tumors to help slow disease after local treatment.
Birmingham, AlabamaAges 18 years+ - NCT05464082RecruitingPhase 2
Collect tumor samples to guide early breast cancer recurrence care
This Phase 2 study tests a “precision” approach using tumor sample testing to help predict, prevent, and treat early metastatic recurrence in triple-negative or hormone-receptor–low, HER2-negative breast cancer. If you qualify, you’ll be asked to provide tumor tissue before (or in place of) standard chemotherapy, so researchers can learn which tumor features matter most.
Salt Lake City, UtahAges 18 years+ - NCT05377996RecruitingPhase 1/Phase 2
Study drug for advanced solid tumors with tumor tissue testing
This early-stage study tests emiltatug leda-dotin (Emi-Le) in people with advanced or recurring solid cancers. It aims to see how the drug works and how safely it can be given, using tumor tissue testing to help understand who may benefit.
Phoenix, ArizonaAges 18 years+ - NCT05366881Recruiting
Blood test study to spot early cancer signal and cancer leftovers
This observational study checks whether a blood test (a “cfDNA” test) can detect early signs of cancer or small amounts of cancer left after treatment. It may help doctors use a simple blood sample to improve cancer detection and follow-up.
Duarte, CaliforniaAges 40 years+ - NCT05377047RecruitingPhase 3
High-precision radiation for limited breast cancer spread
This trial tests a high-precision radiation therapy (called stereotactic ablative radiotherapy) to treat breast cancer that has spread to a limited number of spots in the body. It aims to control the cancer and improve outcomes, and you can join while on your first-line systemic treatment if the cancer is stable.
CorkAges 18 years+ - NCT05388149RecruitingPhase 2
Neratinib plus Kadcyla to treat leftover HER2 breast cancer
This trial studies whether adding neratinib to Kadcyla (T-DM1) can help eliminate “molecular residual disease,” meaning tiny traces of cancer left after surgery and standard HER2 treatment. It’s for adults with HER2-positive breast cancer who still test positive after a short course of Kadcyla, with no signs of cancer returning or spreading on scans.
Toronto, OntarioAges 18 years+ - NCT01840293Recruiting
Breast cancer study using tumor tissue to find key differences
This trial looks at breast cancer “proteins” and molecular features using tumor samples taken during surgery or biopsy. The goal is to better understand why breast cancers behave differently, which may help guide more personalized treatment in the future.
CorkAges 18 years+ - NCT05072314RecruitingPhase 3
Lidocaine drip after breast surgery to improve long-term pain
This Phase 3 study tests whether a long-running lidocaine (a numbing medicine) drip given around the time of breast surgery can improve long-term post-surgery pain and recovery. It may help people who have pain after mastectomy or breast-conserving surgery.
Kingswood, New South WalesAges 18 years+ - NCT05098210RecruitingPhase 1
Personalized vaccine made from your tumor’s new immune targets
This Phase 1 study tests a customized vaccine made from “neo-antigens,” which are new targets found in your tumor. It aims to help your immune system fight certain advanced cancers that have not responded well to prior treatment.
Seattle, WashingtonAges 18 years+ - NCT05095207RecruitingPhase 1/Phase 2
Abemaciclib and bicalutamide for HER2-negative metastatic breast cancer
This Phase 1/2 trial tests whether combining abemaciclib with bicalutamide can slow or shrink HER2-negative, androgen receptor–positive (AR-positive) metastatic breast cancer. It mainly looks at safety and side effects, and also whether the combination can help patients with this type of breast cancer.
New York, New YorkAges 18–90 - NCT04968964Recruiting
Monitoring test for CDK4/6 drugs in metastatic breast cancer
This study follows people with hormone receptor–positive, HER2-negative metastatic breast cancer who are taking CDK4/6 inhibitor treatment (with or without an added blood test called DiviTum®). The goal is to see how well the standard treatment is working and whether DiviTum® (a serum TK1 activity test) can help guide monitoring.
St Louis, MissouriAges 18 years+ - NCT04899908RecruitingPhase 2
Brain radiation with or without gadolinium nanoparticles for brain metastases
This trial tests whether adding tiny gadolinium-containing nanoparticles to standard brain radiation can better control brain metastases from certain cancers. It is for people with tumors that have grown after immunotherapy, are from certain cancers (like melanoma, GI, or HER2+ breast), are cystic, are large, or have come back after prior radiation.
Boston, MassachusettsAges 18 years+ - NCT04771520RecruitingPhase 2
Avapritinib for tumors with specific KIT or PDGFRA changes
This Phase 2 trial studies avapritinib, a targeted medicine, for people whose cancer has specific KIT or PDGFRA genetic changes. It may help shrink or slow growth of certain advanced cancers, including some brain tumors, when standard treatments have not worked or for specific glioblastoma cases.
Houston, TexasAges 18 years+ - NCT04683679RecruitingPhase 2
Radiation plus pembrolizumab and olaparib for certain breast cancers
This study tests whether adding the drugs pembrolizumab and olaparib (or similar “radiosensitizers”) to radiation can improve outcomes for women with advanced breast cancer that is triple-negative or ER-positive/Her2-negative. It’s designed for cancers that have spread or come back and where radiation is being considered to control disease.
Basking Ridge, New JerseyAges 18 years+ - NCT04529044RecruitingPhase 2
177Lu-DOTATATE for advanced breast cancer with targeted receptors
This Phase 2 trial tests whether 177Lu-DOTATATE can slow or shrink stage IV or recurrent breast cancer. It targets tumor “receptors” found on scans, using a radioactive medicine that delivers radiation directly to cancer cells.
Portland, OregonAges 18–100 - NCT04523857RecruitingPhase 2
Abemaciclib and hydroxychloroquine after breast cancer relapse risk
This Phase 2 trial tests whether abemaciclib plus hydroxychloroquine can kill tiny “leftover” cancer cells in the bone marrow after standard breast cancer treatment. It may help lower the chance of cancer coming back by targeting minimal residual disease.
Philadelphia, PennsylvaniaAges 18 years+ - NCT04589468Recruiting
Exercise for cancer survivors at high risk
This study tests whether a structured exercise program can help prevent cancer from coming back in people who have been treated for certain solid tumors (colorectal, ovarian, lung, or breast cancer). If you've completed surgery and adjuvant therapy within the past 2 years and are currently not exercising much, you may be eligible. Participation involves following an exercise plan and regular check-ins.
Durate, CaliforniaAges 18 years+ - NCT04521764RecruitingPhase 1
Vaccine for Metastatic Breast Cancer
This trial tests a vaccine (MV-s-NAP) that is injected directly into a tumor to stimulate your immune system against breast cancer. It is for people with metastatic breast cancer that has spread despite prior treatments.
Rochester, MinnesotaAges 18 years+ - NCT04434040RecruitingPhase 2
Atezolizumab and sacituzumab to prevent breast cancer return
This trial tests two medicines after surgery and chemotherapy to help lower the risk that triple-negative breast cancer comes back. It’s for people whose cancer still showed “residual” invasive disease after neoadjuvant (before-surgery) chemotherapy, and whose blood test shows traces of tumor DNA.
San Francisco, CaliforniaAges 18 years+ - NCT04458532Recruiting
Exercise program to boost heart health after early breast cancer
This trial studies whether a structured exercise program can improve cardiovascular (heart and blood vessel) health in post-menopausal women after early-stage breast cancer treatment. It specifically targets women who have trouble with exercise and have completed cancer treatment within the last 1 to 5 years.
Hartford, ConnecticutAges 21–80 - NCT04348747RecruitingPhase 2
Vaccine plus pembrolizumab for breast cancer in the brain
